. necti n with Wat-e1 FLUSHQM Specification of Letters Application filed April 13, who. Serial No EMA-29.

To a, whom it 777111,. concern.-

Be it known that l, JOHN W. GRANTLAND, a citizen of the United States, res' .ing at Philadelphia, county of Philedelplns, oncl State of Pennsylvenio. have invented certain new and useful Improvement in Flushometei's, of which the following is a specification. I

My invention relates to a. new and useful improvement in WfLl'IGF-ClOSGlJ valves technically called flushoineters, and has for its object to provide valve of this description which contains not only the liushoinetei valve and mechanism. but also a rotary plugvalve. Wheieby the low of Water can he entiiely cut oil.

V lith these ends in. view this invention consists in the details of construction and. comhination oi element-.1 heifeinolteiforth and then specifically designated. by the claim.

in order that those skilled. in the art towhich this invention eppertoins may linden stenil how to make and use the some, the construction and operation will 110W he olescribed in detail, referring to the accoznpenying (ire-Wings, forming a part of this specifies.- tion in Wlll6l1- Figuie 1 is vertical section through my improved valve; Fig. 2 horizontal section token on the line 2 2.- ol Fig.- l showing the plug-valve turned in position to out oliithe supply of Water; Fig. 3, a plan view of the cannot at the upper end ol the valve.

Wheie i'iushon nvelves are used n con- -closets, the cut-oil valves are placed the pipes loo (ling from the valve to the supply-tens; end in order to apply this valve to the supply-pipe it is oftentimes necessary to place the llushometenvelves out at greater distance from the Well than is convenient or else have the pipe extend a. longei distance. with several curves. in order to make space for the 'velve. My int tion is intended to do evvoy with the out-oi v lve in the amply-pipe and place the cut-o l. valve in the l'lushometei Without increasing the size of the flushometei or con'ipliceting the ports to any greet extent.

[L represents the supply-pipe which leecls into the barrel B oi the valve. Fitteil into the barrel B from above with e ground to. pering joint, is the plug-valve C, this plugvalve C being hollow and having on opening l) iormed. through its well communicating with the supply-pipe when the plug-valve is turned in o. certain position; but when the plugwelve is turnerl so that the opening C is out of elinement with the supply-pipe A. the ViEtiJGIlS cutoil entirely from the valve. as shown in Fig. 2.

In. ordinary fiushoinetei-valves o reciprocatingvolve is used, which valve ordinarily operates in conjunction. with the side mine in the bowel of the valve. In my improved. velve the onereting ports of the llushoineter operate in t 'ie some manner except that they operate noon the interior oi; the plug-valve instead oi upon the interior oi the bowel. The uppei portion of the hollow plug-valve C extends above the herrel ll oi the valve, and upon the interior of this upper portion is fitted 8; piston D, Whioh is conneoteo by e hollow stem with a. vertically-ieoiprooeting valve E, adopted to seat lioin shove u. on a seat @11 formed upon the intesioiof the ower end of the plug-waive O. opening is fonneii through the piston D which is oil opted to he closed. poirtiell 1 by e. screw-threaded plug D. which plug isi' ettened upon. one side so as to allow eeeitein amount oi leeltege around the wing, according to the depth it is screwed the soi'eiWtln'eoded opening of the piston. The supply-ope 1g enters through the opening to the inteiz'ioi: of the plug-velve between the piston D and the reciprocating valve- E.

is e. stem. which extenrls upward. through the centei:v ol. the reeipi'oceting velve- E, the piston D and. the tube connecting the two, and on the nope? enl. oi. the stem 1? head is formed (rep-resented at F) adopted. to non in elly seat oven the upper end oi the opening through Whieh the F extends, thus closingthe opening. The stem does not fill .1 ey pass around. said stem The lower end. of the my e linh ivitl'i. disk ll, to which disk the lower end of the link G- eccentrieelly i .oted. The dish. H is connectecl to shaft T :iitonding out of the velve thyough suitable 1 -hoxes, and e tending outward. from this shaft i right angles is e J, to the outer end of which a Weight J is attached. The upper end of the lug -v alve closed end this closed end may he integral with the plug-velveoi' niey be separated for convenience. shown in. the drawings, it consists of e top-nut K, fitting ti htly by e suitohle stol'fing-hox to the top 0 the plugvalve C, end this esp ms tongues K, extend any leakage G1 aii through the openi stein h is eonneo ing out Tom its sides, fitting in notches in the the opening through ivhich it passes, so that v EKG upper end of the dplug-valve, and upon the extreme upper en of the cap-nut a squared lug K is formed, to which a wrench may be applied, and therefore the plug E can be turned at any time by simply applying a wrench to the squared portion K and turning the valve until the opening C is out of alinement with the supply-pipe A.

I do not claim any novelty in the construction-of the reciprocating valve mechanismconstituting the flushometer. This operates in the same manner as other flushometers now upon the market, the operation consisting in raising the rod J and weight J 4 and b so doing turning the disk H, which, througli the link G, raises the stem F, so that the head 'F is off its seat, and after the stem F has the valve is raised, but as soon as the weight J is released it will pull, the head F downward upon its seat, and then the valve will slowly close, the ra idity of its movement being regulated by t e orifice through the piston.

While I have shown this construction of fiushometer-valve, I wish it to be distinctly understood that an flushometer construction could be utilize which can operate upon the interior of a hollow plug E, and I do not wish to be limited to the exact construction here shown, as slight modifications could be made without, departing from the spirit of the invention.

Having thus fully described my invention,

what I claim as new and useful is- In combination, a valve-casing, a supplypipe leading into the valve-casing, an eX- haust-pipe communicating with the valvecasing, a hollow rotar valve-plug for the supply-pipefitting wit 'n the valve-caslng, sai plug having a' valve-seat formed on 1ts interior, a reciprocating valve for the eX- haust-pipe fitting within the hollow plug-and adapted to rest on the valve-seat within the plug, said reciprocating valve having a passage through its upper portion communicating with the portion of the hollow plu above the valve and communicating with t e supply-pipe when the passage of the supply-pipe 1s unobstructed, and means for operating the reciprocating valve. p

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

JOHN W. GRANTLAND.
